JACQUARD-CARD-PUNCHING MACHINE.

Application'filed March 15, 1923. Serial No. 625,373.

To all whom it may concern:

Be it known that I, KEMP S. GRAHAM, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented a Jacquard-Card-Punching Machine, of

which the following is a specification.

My invention relates to machines for stamping jacquard cards, and moreparticularly to that type of machine known asthe piano card stampingmachine.

The main object of the'invention is to provide a machine of this type bymeans of which cards may be punched in practicable manner for theso-called "straight-through tie up of the loom, which operation with thepresent form of machine is practically impossible.

A further object of the invention is to provide means whereby machinesof this type may be employed for duplicating.

The invention further contemplates the provision of novel mechanismwhich in conjunction with a master card prevents the stamping of holesin any other but the i proper points upon the card.

In the attached drawings:

Figure 1, is a side elevation of the essential portions of a machinemade in accordance with my invention;

Fig. 2-, is a front elevation of the machine;

Fig. 3, is a fragmentary plan view illustrating the principal details;

Fig. 4, is a side elevation of that portion of the mechanism illustratedin Fig. 3;

Fig. 5, is a section on the line 55, Fig. 4;

Fig. 6, is a section on the line 66, Fig. and

Fig. 7, is asection on the line 7 7', Fig. 3.

Vith reference to the drawings, the ma chine is of the same generalconstruction as the machines of this type now in general use, comprisinga frame 1 having at the top a table 2, upon which travels a carriage 3provided at its'forward end with means for clamping one end of a card.Near the forward end of the table 2 is mounted upon vertical slides t apunching-head 5, which head contains the punches by means of which thecards are perforated, this head being provided with. the usual set ofkeys 6 by means of whiclf the desired punches, designated in thedrawings by the reference numeral 7, are thrown into operation. Theslides 4 with the head 5 are reciprocated vertically by means oftreadles 8 and 9, depression of which respectively elevates anddepresses the head. The slides 4, at, are provided with a cross head 10,in which is pivotally secured intermediate its ends a lever arm 11. Theforward end of this arm 11 is fulcrumed at the top of a vertical-arm l2pivotally secured at 13 to a cross beam 14L of the frame 1,thearrangement being such that elevation or depression'of the rear endof the arm 11 effects a vertical reciprocation of the cross head 10 andof the guides :l'. to which the cross head is secured; The rear end ofthe arm 11 is connected through rods 15 and 16 and a rockarm 17 securedto the under side of the table 2 to't'hetreadle 8, the treadle 9 alsobeing connected to the rear end of the lever 11 through a connecting rod18. As'previously stated, by means of the foregoing apparatus depressionsuccessively of the levers 8 and 9 effects a vertical reciprocation ofthe punching-head The usual means also is provided for i11- termittentlyadvancing the carriage 3 on the the movement of the punching-head 5.Movement of the carriage 3 is provided for in the usual manner byoperatively connect ing the treadle 8 with an escapement mechanism, sothat at each downward move ment of this treadle 8, the carriage underinfluence in the present instance of an attached weight 19 is permittedto advance a predetermined distance towards the rear of the machine andaway from the punching-head 5.

The escapement, which comprises a rack 20 at oneside of the carriage anda pair of VGl't-lCilllY':lllOYklblB spaced blades 21-and 22 is actuatedfronrthe treadle 8 through a rock lever 23 mounted on the table 2 at oneside of the carriage and t-o which the blades 21 and 22 are operativelyconnected, and a rod 2 L which connects the forward end of the lever A3to the treadle 8. The blades 21 and 22' are carried by a block 25 havinga lateral extension 26 which projects into a horizontal slot 27 in therear end piece 28 of the lever 3, the arr; ngementbeing such thatoscillation of the rock lever 23 will effect 'a vertical reciprocationof the block 25 which is guided in its vertical movement by two uprightpins fastened to the table 2. A transverse arm '29 secured to the block25 table 2, this movement synchronizing with bridges the path of thecarriage 3 and has on the outer end a vertical guide pin 30 slidable ina guide 31 secured to the table 2. In far as described, the mechanism isidentical in substance with a well known standard machine of the typeinvolved, and the operation of the mechanism will be understood by thoseacquainted with the art. The transverse arm 29, as illustrated in Fig.7, comprises in that portion overlying the path of the carriage 3,horizontal and parallel branches 32 and 33, and vertically slidable inthese branches are a series of pins 3st which correspond in number tothe punches T of the punching-head and which occupy similar relativepositions, the pins Z-E-l being in alignment. with the path of thecarriage 3 and with the respective corresponding punches 7 Secured tothe top of the carriage 3 is a platform or table adapted for receptionof a master card, designated in the drawings by the reference numeral36, means being provided such as a peg 37 for retaining the card inplace upon the platform. The platform 35 is perforated over its entirelength, the perforations being in transverse rows the distance betweenwhich corresponds exactly to the distance to which the carriage ispermitted to move by the previously described escapement. Each row ofthese apertures contains perforations corresponding in number to thenumber of punches 7 and of the pins 84, and the in dividual perforationsin each row are correspondingly spaced. Each of the pins 34 I isprovided with a spring 38 which tends to move the pin downwardly to thepoint where its lower end rests upon the surface of the card 36 or,where the card is perforated, to a detruded position, illustrated inFig. 7, which is governedby stop pins 39 extending laterally through thepins 34 and constituting also an abutment for the lower ends of thesprings 88. Each of the pins is pivotally secured to one arm of abellcrank lever it), which levers are loosely mounted upon a shaft a lextending transversely of the table 2 and mounted inthe tops of a pairof uprights 42, 42, secured to the table. The other arms of these bellcrank levers n are secured by means of reach rods 43 to a series ofblocks 4% slidably mounted in horizontal recesses in the side of thepunchinghead 5., as best shown in Figs. 5 and 6. As clearly illustrated,one of the blocks ll underlies each of the keys 6, and the inner ends ofthe rec in which the blocks move overlie respectively the punches T whenthe latter are in the normal depressed position.

Each of the. blocks it is provided atits inner end with a verticallyslidable pin or plunger which occupies a vertical passage in the innerend of the block. the pins being retained within the passages by acollar 46 which normally rests upon an internal shoulder 4.7 in theblocks. The pins a5 when the blocks 44; are in the positions illustratedin Fig. 6 directly overlie and are in alignment with the punches 7 sothat elevation of the punch in the head. will effect a correspondingelevation of the pin i=5. The keys 6 are normally held in an extrudedposition by a spring 50, and in this position the inner ends of the keyslie outwardly of the inner end of the blocks 44: and of the pins eta")whereby the said pins *5 are free to move upwardly. lVhemhowever, thekeys 6 are pressed inward, the inner ends thereof are brought directlyover the tops of the apertures in the blocks l4: occupied by the pinswhereby elevation of the pins is prevented. Retraction of the blocks 44,in .a manner hereinafter described, whereby the inner ends of the blocksare made to clear the tops of the punches '7 permits elevation of thepunches regardless of the position of the keys 6. i

In the position of the block 25 illustrated in Fig. 7, it will be notedtl at the pins 3% rest upon the unperforatcd portions of the master card36, while those pins which overlie perforated portions pass throughthrcard and through the platform 35. its a result of the detrudedpositions assumed by these latter keys, which are designated in thedrawings by the reference numeral 52, those of the. bell crank levers e0which connect with these pins are so moved, under the action of thesprings 38, as to advance the rods 43 and to move the blocks 4% inwardlyin the head 5 to the position illus trated in Fig. 6. With the blocks tsin this posit-ion and with the key 6 in its inner position, the punch 7is prevented from moving upward. Those of the pins 3* however, whichrest upon the top of the card 36 retain the bell crank levers 1-0 towhich they are attached in such position that the blocks ie are held intheir retracted, outer positions in which the inner ends of the blockslie clear of the tops of the punches '7 whereby the punches arepermitted to move upwardly in the head regardless of whether the key 6is in or out.

It will also be noted that at each upward movement of the block 25,those of the pins 3% which have passed through apertures in the card 36and the platform are first elevated out of these apertures to theposition of those of the pins 34: whicn rest upon the top of the card86, and an additional final upward movement of the block effects an.elevation of the entire set of pins 34 above the top surface of thecard, thereby breaking contact between the pins and the card 36 duringthe advance movements of the carriage 3. The operation of the machine isas follows: A blank card, designated in Fig, c

by the reference numeral 53, is passed under the punching-head 5 and itsinner end secured by means of the usual clamp 54 to the forward end ofthe carriage 3. An op erating lever 54 is provided on the carriage formanipulating this clamp 54. The operator with a color chart before himthen manipulates his keys 6 in accordance with the chart. Previous tothe starting of the machine, however, the master card 36 has been placedupon the platform 35 of the carriage, this master card being soperforated as to permit the punching of the card 53 only in accordancewith the particular tie-up of the machine with which the card 53 is tobe used. This control is effected through the pins 34: and the blocks Mto which they are connected, since only when the pins 34: are permittedto pass through the card 36 is it possible for the corresponding punch 7in the punching head to perforate the card 53. The operator accordinglyneed not keep in mind the tie-up and need manipulate the keys 6 only inaccordance with the color arrangement of the color chart, the keys beingmanipulated as a unit. The operator operates the treadles 8 and 9 in'theusual manner to depress and elevate the punch-head, each depression ofthe lever 8 resulting in an elevation of the head and the depression ofthe forward end of the lever 23 with a resultant actuation of theescapement to permit a rearward movement under the action of the weight19 of the carriage 3. Each actuation of the escapement to release thecarriage 3 also results, as previously described, in an elevation .ofthe pins 34 clear of the card 36 whereby the pins 34 do not interferewith the following movement of the carriage.

When it is desired to move the carriage forward to the startingposition, a third treadle 55 is provided which is connected by means ofa rod 56 with the forward end of the lever 23 whereby depression of thetreadle 55 elevates the lower blade 22 of the escapement clear of thetop of the rack and thereby permits advancement of the rack by means, inthe present instance, of a flexible element 57 such as a rope which isattached to the carriage and which is carried forward to a positionavailable to the operator.

It will be noticed that the rod 56 passes through an aperture in theforward end of the lever 23 and is provided with a nut at its upper endwhich, .when the rod is de-' pressed with the lever, carries the lever23 downwardly, the arrangement, however, leaving the lever 23 free tomove downward under operation of the treadle 8 without affecting thetreadle 55, which is normally retained in an elevated position by aspring 58.

The great advantages of this invention will be recognized by thosefamiliar with the art. since it enables the cutting of cards for certaintypes of tie-up which heretofore could not be cut in practicable mannerupon this type of machine. The device thus greatly increases the scopeof this type of machine as well as materially facilitating the cuttingof all cards. The device further permits duplication by the simpleexpedient of placing the card which is to be duplicated up on theplatform 35, and after pressing all of the keys 6 manipulating thetreadles 8 and 9 until the card is completed.
